Lamination method and lamination device

Abstract

To provide a technique for automatizing a lamination work of a woven prepreg material. A lamination order is decided. A plurality of piece parts 10 is cut out from a prepreg base material. In accordance with the order, the cut-out piece parts 10 are placed on a base sheet 20. The base sheet 20 having the piece parts 10 placed thereon is wound into a roll shape. The base sheet 20 is fed from the feeding reel 31 to be wound by the winding reel 32. A compaction roller 33, in accordance with the order, causes the piece parts 10 to be pressure-bonded against a jig 40 or a laminated body (in the middle of formation) to transfer the piece pats 10 from the base sheet 20. Repetition of the above operations enables lamination of the prepreg materials and achieves formation of a targeted laminated body 50 (final product).

1 . A lamination method for laminating prepreg materials which are made by impregnating fibers with an uncured resin, the method comprising:
 a step of deciding a lamination order for laminating a plurality of piece parts made of the prepreg material;   a step of cutting out the piece parts from a prepreg base material made of the prepreg material;   a step of placing the cut-out piece parts on a belt-like shaped base sheet in accordance with the order;   a step of winding the base sheet having the piece parts placed thereon into a roll-like shape;   a step of setting the roll-like shaped base sheet to a feeding reel and setting an end part of the roll-like shaped base sheet to a winding reel;   a step of feeding the base sheet from the feeding reel to wind the base sheet by the winding reel; and   a step of pressure-bonding the piece parts against a jig or a laminated body in accordance with the order by using a compaction roller to transfer the piece parts from the base sheet.   
     
     
         2 . The lamination method according to  claim 1 , wherein the compaction roller adjusts a tensile force of the base sheet for each of the piece parts when pressure-bonding the piece parts against the jig or the laminated body in accordance with the order. 
     
     
         3 . The lamination method according to  claim 1 , wherein the fibers of the prepreg material have a woven fabric shape. 
     
     
         4 . The lamination method according to  claim 1 , wherein the plurality of piece parts includes piece parts having different sizes or/and different shapes. 
     
     
         5 . The lamination method according to  claim 1 , wherein the jig has a curved surface. 
     
     
         6 . The lamination method according to  claim 1 :
 wherein the base sheet has a front surface having the piece parts placed thereon and a back surface which is a reverse side of the front surface; and   wherein the back surface has better releasability than the front surface.
